Product Description

Usage and characteristic

The product has two columns with horizontal center breaks. It is used for breaking or connecting HV lines under no loads in the substation. It
accessible to the grounding switch on one side or two sides.
The disconnect switch adopts CJ2 or SRCJ motor operating mechanism to realize the three-gang operation. The earthing switch adopts
CS14G manual operating mechanism to realize the three-gang operation.

Service condition
a) Ambient temperature:        -60ºC~+55ºC;
b) Altitude above sea level:    not exceed 2000m;
c) Wind speed:                       no more than 34m/s;
d) Iced thickness:                   no more than 10mm;                        
e) Earthquake:                        intensity no more than 9 degree;
f) Dirtiness condition:              suitable for pollution region IV class and below;
g) No heavy shock frequently, no explosive substance, inflammables or caustic;
h) The intensity of sunshine:   1000W/m²(It is a fine day at noon)

Characteristic:
1. Application of friction type contacting structure in main knife moving conductive contact surface; 
2. Auto-locking device of breaking and closing positions effectively prevents the separation of dynamic/static contacts due to wind or electric
    motive force;
3. The application of non-oil bearing and copper alloy sleeve on rotating point making it have auto-lubrication function and conquers the
    corrosion and seizure of the rotating point;
4. Application of advanced surface processing technique and anti-rust aluminum, stainless steel greatly enhances surface anti-rust property;
5. Three-pole linkage and electric/manual operation of main switch;
6. Fitted with earthing switch that has the same short-circuit current withstand capability disconnector;
7. Effective prevention of mal-operation by electric/mechanical dual interlock between disconnector and earthing switch.
